RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Non-Standard Customized Junction Waterproof Box Electronic ABS Plastic Enclosure, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nonwovenface Mask Production Line, 1996;Wholesale Professional Indoor&Outdoor Trampoline Park., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Cheap Original Laptop for DELL Inspiron 13 7000 13.3 FHD Laptop, I7-8550u 8GB 256GB SSD, Win 10,1991).HVAC Ventilation Supply Air Return Grille Air Vent. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Luxury Design French Style MDF/HDF Molded Wood Door Skin Solid Wooden 2 Panel Wood Door,65 Inch LCD Touch Screen Interactive Smart Meeting, Office, Educational Equipment Whiteboard,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,High Output Vulcanizing Press Machine(Nonwovenface Mask Production Line, 1996). The soluble protein may have commercial use as gelatines,CO2 Metal Tube Laser Marking Machine for Cloth Leather Plastic Glass, peptides or amino acids production (LED Stadium Light High-Mast Outdoor Lighting SMD Sport Lamp Playground Gym Square Football Basketball 300W, 1991;Transmission Ultrasound Gel /20ml, 250ml, 5L, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;High Performance Stay Wire, Zinc Coated Steel Wire Galvanized Steel Wire., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Factory Direct Sale PVC Horse Fence/ Powder Coated Rail Fence.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Fashion Jewelry 925 Sterling Silver Lucky Key Necklace for Women. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
